CONTROLLING DEVICE.

Application filed December This invention relates to certain novel anduseful improvements in controlling devices and has for its principalobject the production of a device of this character wherein provision ismade for operating control mechanism through the medium of a time piece,as for example an alarm clock.

A further object of the invention is the production of a device or" thischaracter wherein a novel releasing arrangement is provided undercontrol of a timepiece such as above mentioned.

A further object of the invention is the production of a device of thischaracter wherein provision is made for automatically controlling avalve or similar device through the medium of a novel controlarrangement operable by a time piece as for exan'iple an alarm clockwherein by setting the alarm v0t the clock the control will be releasedby unwinding oi the alarm spring of the time piece.

.Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of partsto be here-- inafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings illustrating the prefer "ed. form of construction and in which:

Fig. 1 is a side elevational view of the invention showing the same inlockingposition, 7

Fig. 9. is a sectional view of the same taken substantially on line ofFig. 1,

Fig. 3 is a view similar to that illustrated in Fig. 1 showing theiiwention in released position,

Fig. 41 is an elevational View taken substantially on line l-4t of Fig.1,

Fig. 5 is a sectional detail view of the invention taken substantiallyon line 5 5 oi Fig. 1, and

Fig. 6 is a fragmentary sectional detail of the invention takensubstantially on line 66 of Fig. 1.

Referring particularly to Fig. 1, 1O indi- "ates a conductor pipe and 11a valve of an approved type controlling passage through the conductorpipe and provided with an operating head 12. The pipe 11 passes throughand supports a housing 13 having a hinged side wall 14 and fixed walls15 providing a compartment 16 within which is located. a triggermechanism and valve contro em- 7, 1925. Serial No. 73,831.

bodiedin the invention and hereinafter described. y

The trigger mechanism includes a supporting rod 17 mounted in parallelspaced relation with the inside surfaces of the wall 15 by angled endportionslS fixed thereto as at 19 by any suitable means. Adapted foradjustmentlongitudinally oil the supporting ,rod 11 1s a link member 20connected to the supporting rod by means of a slide 21 havmg spacedangled end portions provided with aligned slots :23 for passage of thelink and rod and provided with a wedging member 24% adapted whenoperated in a certain direction to move the link member 20 into clampingrelation with the rod as best illustrated in Fig, 6. i This wedging camis pivolally connected to the slide by means of pivot pin The link 20 isprovided with a horizontal portion 2-6 looped as at 26 for connectionwith a release linger 27 at one end thereof. The release linger has itsopposite end adapted for insertion through a loop 28 formed in aretaining linger 29 having an end in connection with the lower end 30 ofthe link member. This retaining linger 29 has a portion 31 forengagement with an angled en'd portionBQ formed as an integral part "ofa trigger arm 33.. The trigger arm 33 extends through a slot 32 througha bearing plate 33 fixed to the wall in any suitable manner.

The releasing finger 2? is adapted for r leasable connection with achain ill having one of the links 34: thereof connecied to an operatingarm 35 fixed to the operating head 12 of the valve 11. This operatingarm 35 is preferably iorn'ied of a member of substantial n'iaterial bentsubstantially U- shaped with its bight end portion fixed to theoperating head 12 by rivets 12 or other suitable means. To the link 34:attached a supporting cable 36 passing over a ,pulley 37 located abovethe valve and the connection with the angled end por ion 32, releasingthe releasing finger 27 from engagen'ient with the loop 28. Upon releaseof the releasing finger the gravity weight drops down drawing the cable36 over the pulley 37 operating the controlling arm 35 which operatesthe valve by reason of its connection to the operating head 12 thereof.

The adjustability between the supporting rod 17 and the link member 20permits vertical adjustment of the releasing member, above described, tocompensate for the position of the trigger arm 33 which is also mountedfor adjustment longitudinally with respect to parallel spaced guide rods39 having angled end portions ell) fixed to the wall 15 by suitablemeans. i

As best illustrated in Fig. 5, a clip ll is pro ided with curled ends 42adapted for slidable relation with the guide rods 39 and provided withan opening permitting passage of the end of the trigger arm. The end 43of this arm is provided with an enlarged head ll ofsnbstantial size toWhich a connector member 45 is secured by soldering or the like. Thisconnector serves to connect the trigger arm to the alarm winding key 46of an alarm clock 4l7. The connector as shown is preferably formedsubstantially li-shaped with its bight portion 48 fixed to the head 44as above mentioned and provided with aligned slots 49 in its oppositeresilient limbs l5 for the reception of the adjacent portions of thering 50 of the winding key. This ring 50 is locked in the slots 49through the medium of a lock strip 51 struck from one of the limbs 45and extended through a slot 52 formed in the other of the limbs andlocked in this position by a lock pin 53 inserted between a curledportion 5% and the adjacent limb. The lock pin attached to one of thelimbs 45 through the medium of a flexible member 55 and upon withdrawalof the pin from locking position the limbs of the connector spring inthe opposite direction disengaging the ring from the slots permittingremoval of the alarm clock.

By adjust-ably mounting the trigger arm it is apparent that the same canbe elevated or lowered to compensate for the height of the ring ofvarious makes of time pieces.

From the foregoing description it is apparent that when the alarm springof the alarm clock 47 unwinds the key thereof is caused to rotate and inturn will cause the trigger arm to also rotate by reason of itsconnection thereto in the manner described above and as this triggerarmcontinues to rotate it releases the retaining finger 29 in the mannerand for the purposes herein described.

While I have illustrated and described the invention for use incontrolling the valve of a conductor pipe it is apparent that the samecan be used for controlling an electric switch or other controllingmechanisms without destroying the utility of the invention or departingfrom the spirit thereof.

While I have shown and described the preferred form of the invention itis to be understood that various changes and alterations may be carriedout in manufacture without departing from the spirit of the invention orthe scope of the appended claims.

The invention having been set forth, what I claim as new and useful isl. A device of the class described including a supporting rod, a linkmember juxtaposed said rod, a slide adapted to retain said link memberin sliding engagement with said rod a release member connected to saidlink member at one end thereof a retaining finger connected to the otherend of said link member and adapted to 'releasably retain said releasefinger, and a trigger arm disposed to engage said retaining finger andadapted to move said finger from engaging position at predeterminedtimes. a

2. A device of the class described including a supporting rod, a linkmember juxtaposed said rod, a slide adapted to retain said link memberin sliding engagement with said rod, said link having a right angularlyextending portion at one end thereof, a release finger pivotallyconnected to said link at the outer end of said right angularlyextending portion, a retaining finger pivotally connected to theopposite end of said link and having a. portion formed therein adaptedto releasably retain said release finger in substantially parallelrelation with said supporting rod and a rotatably mounted trigger armhaving an angularlv disposed portion adapted to engage the free end ofsaid retaining finger whereby to free said release finger when saidtrigger is rotated.

In testimony whereof I afiiX my signature.
